BRUSH Filed May 27, 1964 INVENTOR; HEINZ HELMKEN ATT'YS United States Patent Office 3,271,806 Patented Sept. 13, 1966 3,271,806 BRUSH Heinz Helmken, 2921 S. 12th Ave., Broadview, Ill. Filed May 27, 1964, Ser. No. 370,434 1 Claim. (Cl. 15-176) The present invention relates to an improvement in a brush, and, more specifically, to a brush having a readily detachable, angularly-inclined brush-head. The brush according to the present invention has been found particularly useful for painting and the like, and particularly to provide for reaching places and things easily wherein the user would normally encounter difficulties and even dangers in using the common paint brush.

Accordingly, one object of the present invention is to provide a new and improved brush.

A further object of the present invention is to provide a new and improved paint brush.

Yet a further object of the present invention is to provide a new and improved brush having a readily interchangeable brush-head.

Yet a further object of the present invention is to provide a new and improved brush provided with a head angularly inclined to the longitudinal axis of the brush.

A further object of the present invention is to provide a new and improved brush-head wherein the bristles of the brush and the means for securing the brush-head to the handle are embedded in suitable potting compound.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claim annexed to and forming a part of this specification.

In accordance with these and many other objects of the present invention, there is provided a new and improved brush, of the type particularly useful as a paint brush, but which may have other purposes, and including an elongated handle having a head-engaging surface at one end angularly disposed to the longitudinal axis of the handle. A through aperture is provided in the head-engaging surface normal to the surface to provide for the attachment of a brush-head. Additionally there may be provided interchangeable brush-heads, each including a cylindrical metal sleeve retaining a plurality of bristles which extend axially out of one end of the sleeve, and a fastening screw extends concentrically through the sleeve and extends axially out the other end of the sleeve. Suitable potting material fills the sleeve both to secure the bristles and to imbed a portion of the screw. The screw is adapted to extend through the aperture in the handle so that the brush-head may be interchangeably secured to the handle by a suitable wing nut or other means.

The present invention also relates to the new and improved interchangeable brush-head.

Advantageously the present invention allows the reaching and painting of places and things easily, where the user would encounter difficulties, and perhaps even danger, in using the common paint brush. One specific application of the present brush may be for the internal painting or cleaning of rain spouts. Moreover, it is easy for the user to change one head for another should he have need for it; for example, when working with oil-base paints, a hog bristle brush may be best, whereas when working with a latex or other water-base paint, a nylon brush is preferable.

For a better understanding of the present invention reference may be had to the accompanying drawing wherein:

FIGURE 1 is a perspective view of the improved brush as used to paint or clean the inside of a rain spout;

FIGURE 2 is a perspective view of the improved brush of FIGURE 1, and drawn to a larger scale than in FIG- URE 1;

FIGURE 3 is a partial plan view of the improved brush of FIGURE 1; and

FIGURE 4 is a partial elevational view, in broken away sections, of the brush of FIGURE 1.

Referring now to the drawing, there is illustrated an improved brush 10 according to the present invention. The brush 10 is made in two parts, namely an elongated handle 12 and a brush-head 14. The brush-head 14 is interchangeable with other similar brush-heads on the handle 12 so that a proper brush-head 14 may be selected for a particular job. Moreover, as clearly illustrated in FIGURE 1 the brush-head 14 is angularly disposed to the longitudinal axis of the handle 12 so that the brush 10 may readily be used for cleaning the internal channel of a drain gutter 15 or other hard to reach place.

The handle 12 is generally circular in cross-section, dimensioned to fit the palm of the hand, as best illustrated in FIGURE 1, and is provided at one end with a brush-receiving dome 16, spherical in outer configuration, and provided with a circular head-engaging planar surface 17 angularly disposed to the longitudinal axis of the handle 12. The handle 12 may be formed of any suitable material, and in the illustrated embodiment, is of wood. The dome 16 is provided with a through aperture 18, normal to the brush-receiving surface 17 for receiving the brush-head 14.

The brush-head 14, in the illustrated embodiment, includes a plurality of bristles 22 extending axially out of one end of a cylindrical metal sleeve 23. Additionally a screw 24 extends concentrically through the sleeve 23 with its head 24a at one end of the sleeve 23, and having a threaded portion 24b extending through the aperture 18. Suitable potting compound 26 fills the sleeve 23 to secure the bristles 22 and to imbed the shank of the screw 24. A washer 27 may be positioned under the head 24a of the screw 24 to aid in preventing the screw 24 from pulling through the potting material 26.

In order to detachably secure the brush-head 14 to the handle 12, there is provided a wing nut 30 on the threaded portion 24b of the screw 24 which extends through the aperture 18. A washer 31 may be positioned under the wing nut 30. Moreover, the dome portion 16 of the handle 12 may be provided with a suitable bearing sur face 32 as by counterboring or bossing around the aperture 18.

In one embodiment of the invention which has been found suitable, the brush-head 14 made an angle (1, FIGURE 4, with the longitudinal axis of the handle 12 of approximately Moreover, the handle 12 was approximately 18" long. The bristles 22 extended approximately 1%" below the sleeve 23 and formed a brush-head 1%" in diameter.

Although the present invention has been described by reference to only a single embodiment thereof, it will be apparent that numerous other modifications and embodiments will be devised by those skilled in the art which will fall within the true spirit and scope of the present invention.

What is claimed as new and desired to be secured by Letters Patent of the United States is:

A brush comprising an elongated handle having a headengaging pl-anar circular surface at one end angularly disposed to the longitudinal axis of said handle and provided With a concentric through aperture normal to said surface; and a brush-head including a cylindrical metal sleeve open at both ends, a plurality of bristles extending axially out one end of said sleeve, a screw extending concentrically through said sleeve and extending axially out the other end of said sleeve, potting material filling said sleeve securing said bristles and imbedding a portion of said screw, said screw extending through said aperture in said handle, and nut means on said screw securing said brush- References Cited by the Examiner UNITED STATES PATENTS 10/1886 Dessau 15-169 6/1888 Nicol 15-191 2/1891 Hardie 15-176 X 3/1929 Jensen 15-192 12/1934 Stevens et al.
